BARREL-WASHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 443,751, dated December 30, 1890.

Application filed October 25, 1887. Serial No.253,373. No model.)

To all whom it may concern:

Be it known that we, ULRICH EBERHARDT and HENRY E. EBERHARDT, citizens of the United States, residing at Newark, Essex county, New Jersey, have invented certain new and useful Improvements in Barrel- \Vashing Machines, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to that class of barrel-cleaning machinery in which the barrelis supported by means of india-rnbber rollers fixed on two parallel shafts, and is rotated by such rollers in contact with brushes at its ends and top; and the object of my invention is to render the entire construction more rigid and durable, to permit the convenient replacement of the shaft-bearin gs when worn, and to renew the rollers when they become worn by use, to facilitate the adjustment of the shafts toward one another when the rollers are partly worn, and to facilitate the adjustment of the brushes to and from the ends of the barrel and to different heights upon the frame.

The invention consists partly in the particular construction of the stanchion, by which a vertical central opening is provided in which the brushes may be inserted and adjusted against the ends of the barrel, the post of the stanchion at each side of the central opening being formed in one piece with boxes, which are provided with recesses to sustain the shaft-bearings; and it also consists in various details of construction to facilitate the introduction of the bearings to the recesses within such boxes and the means of adj usting the bearings and the brush-holders.

In the annexed drawings, Figure 1 is a view of the base of the stanchion and its attachments in the simplest form of construction. Fig. 2 is a plan of the stanchions and the roller-shafts, the stanchions being shown in section on line y yin Fig. 1. Fig. 3 is afront view of the machine. Fig. 4 is an end view of the same from the right of Fig. 2. Fig. 5

is a sectional plan on line w :0 in Fig. 3. Figs.

6 and 7 are respectively a side View and a plan of one of the removable bearings, and

Figs. 8 and 9 are respectively an end view and a plan of one of the adjusting-blocks. Fig. 10 is a side view, similar to Fig. 4, of the bearing J showing the studs J 4 and illustrating their position upon the side of the bearing similar to that of the lugs J Fig. 11 is a plan of the block L, similar to that shown in Fig. 2; and Fig. 12 is an elevation of its inner side, showing clearly the longitudinal groove L formed toclear the, studs J when the block is shoved into the recess by the side of the bearing L, having the projecting'studs J Figs. 1, 2, 6, 7, 8, 9, 10, 11, and 12 are drawn upon a larger scale than Figs. 3, 4t, and 5.

A is the bed of the machine, and B B the stanchions, shown herein constructed, each 7 with two posts, having each an inner rib B and separated by a vertical space B 0 is a beam bolted to the tops of the stanchions to supportthe holders for the top brushes.

C are water-pipes perforated in the usual I manner to throw jets of water upon the barrel.

D D are the parallel shafts having rubber rollers E for supporting and rotating the barrel and provided with sprocket-wheels F, connected together by means of a chain F, and one of the shafts is provided in addition'with pulleys G, to which the belt for driving the shafts is applied.

H and H are respectively the top and the side brushes.

Each of the stanchions is shown herein formed with two vertical posts or standards arranged at the opposite sides of a vertical central opening and united at their tops and bottoms to give them the desired rigidity. Upon each of such posts, at the proper height from the bed of the machine, is formed a box I, containing a recess Pto receive and support the shaft-bearings. The upper brushes H are secured within holders H pivoted at the lower ends of the vertical rods H which are suspended from a cross-bar 1-1. Such cross-bar is sustained adjustable in vertical guides P upon the frame (3 by means of a screw P, which is raised and lowered by means of the hand-wheel P as in similar constructions. The recesses may be provided with detachable caps to remove the bearings ICO from the recesses laterally, or the box I may wholly inclose the recess, in which case the shafts and bearings would be inserted through the recesses longitudinally. In either case the recesses I are made wider than the bearings, and the extra space at either side of the recess may then be filled by an adjustingblock of suiiicient thickness to fill such space.

\Vhen the supporting-rollers are now, these adjusting-blocks are intended to be inserted in the inner ends of the recesses, the blocks being lettered L in Figs. 4 and 5, and shown inserted between the bearings of the two par allel shafts in such figures to hold the bear ings and shafts as far apart as possible. When the rollers become worn, the blocks may be withdrawn from the inner ends of the recesses and the bearings moved toward one another, the blocks then being inserted in the outer ends of the recesses and the movement of the shafts toward one another being equal to the total thickness of the two blocks.

\Ve prefer to form the boxes I with removable caps 1, (shown in Figs. 3, 4:, and 5,) so that the bearings lettered .T in such figures may be removed laterally from the recesses with the friction-rollcr shafts D. The bearings, which are shown enlarged in Figs. 6 and 7, are formed in two separable parts connected by ears J 2 and bolts J and are provided upon their upper and lower sides with ribs J to hold them fromlongitudinal movement. The blocks L, for use with such bearings, are shown detached in Figs. 8 and 9, and are provided with flanges L at their opposite ends to hold them in place in the recesses.

In Figs. at and 5 the blocks are shown inserted in the inner sides of the recesses to hold the shafts D separated as widely as possible, as would be done when the supportingrollers E are new.

In Figs. 1 and 2 the boxes I are shown without removable caps, and the bearings and adjusting-blocks are therefore made to be removed longitudinally.

The bearings lettered J are shown solid, and the adjusting-blocks (shown separately in Figs. 11 and 12 upon a larger scale) are formed with a flange L at only one end, so as to be removed from the side of the box by drawing the block parallel with the shaft D. Studs J are formed upon opposite sides of each bearing J to embrace the opposite edges of the box I, as shown in Fig. 2, to prevent the longitudinal. movement of the bearing in the recess, and to permit the introduction of the adjusting-block past such studs. The in ner side of the block lettered I. in Figs. 1, 2, 11, and 12 is formed with a longitudinal groove L The block is formed long enough to extend through the recess, and is provided with a pin L, inserted against the side of the box I to hold the blockin the box. \Vhen the supporting-wheels E are partially worn, one of the adjusting-blocks may be placed upon the inner side of the slnift-bearing and the lowering the same.

other upon the outer side, as shown in Figs. 1. and 2, and both the blocks may be placed upon the outer side of the bearings when the wheels require a still closer adjustment toward one another.

\Vith the construction shown in Figs. 3, 4, and 5 itwill be seen that when the rubber rollers need renewal it is not even necessary to remove the chain connecting the two supporting-shafts when removing them from the machine to change the rollers. \Vith such construction this is done by removing the pins 1 and the caps I from the recesses, so

as to swing the end of the shaft opposite that having the chain-wheel from the recess, when the bearing may be removed from the shaft, and the rollers E can then be slid off and replaced by new ones without the slightest dithenlty. In such an operation the hearing at one end of the shaft merely assumes an inclined position within its recess, while that at the other end is wholly withdrawn from the re cess to be removed from the shaft. After the new rollers are applied the detached bearing is applied to the shaft and inserted in its recess, when the replacement of the caps I and pins 1 restores the machine to its working condition.

The carriers for the end brush-holders K consist of cross-heads M, fitted within the spaces B and grooved at their ends to fit the ribs B upon the stanchions, and supported from the top of the stanchions by the screwrods N, rigidly secured at their lower ends to cross-heads M,and having near their upper ends tapped hand-wheels N for raising and The rod N projects through a bearing N formed in the top or arch of the stanchion, and is threaded to fit the tapped hand-wheels, which thus serve as nuts when turned by hand and operate to adjust the brush-holders K at the proper height. The cross-heads are provided with transverse guides M, fitted to the brush-holder to prevent its turning when the machine is in operation. The shanks of the brush-holders K are slotted to fit the screw-rods N and are clamped upon the eross lzeads between the guides M. by means of a nut N upon the screw-rod.

is a wrench, shown in section in Fig. 4.=, and provided with a socket fitted to the nut N and with a handle projecting from the socket to turn the nut when required.

To clamp the erossheads M to the stan chions, 1 constructeach with. a loose plate MI, provided with a bolt M It will be understood from the above de* scription that the rod N performs a double function and not only serves to suspend and adjust the eross-hcad in the opening B, but by the formation of a thread upon the rod adjacent to the cross-head to fit the nut N the rod serves as a means of clamping the brnslrholder K upon the crosshead. The rod N passes through the slot in the brushholder as well as through the nut N and eye of the wrench N and it is therefore necessary to apply the nut, brush-holder, and Wrench to the rod in the proper order during the construction of the machine. By formin g the brush-holder and wrench in such manner their displacement or removal from the machine is wholly impossible and they are always ready for use in the desired manner. The two posts of the stanchion may be integrally connected at the top and bottom by forming them in a single casting, as shown in the drawings, the boXesIbeing formedintegral with the stanchions by such process, and the recesses 1 formed ready to receive the shaftflbearings in the cheapest possible manner.

The casting of the two posts in one piece with the boxes integral and with the central opening between the posts adapted to receive the cross heads M greatly diminishes the number of parts required in the construction of the machine and greatly reduces the labor of handling and fitting up the parts in the construction of the machine.

Ve have already stated the advantage of placing the slotted brush-holder upon a horizontal cross-head instead of upon the side of a vertical post, and a great advantage in the rigidity and durability of the shaft-bearings is secured by having their opposite supporting-boxes formed in the same casting, as shown in the stanchion herein, and thus avoiding the chance of their being shifted or loosened by wear, as when bolted separately upon a bed-plate.

Having thus set forth our invention, what I we claim herein is- 1. In a barrel-washing machine provided with friction-rollers to rotate the barrel, the combination, with a suitable bed, of a vertical stanchion at each end of the bed, formed with two vertical posts B at the sides of an intermediate space B boxes I, formed in such stanchions and having recesses for rollershaft bearings, bearings fitted within the same and secured removably therein, and friction-roller shafts rotated within such bearings, substantially as herein set forth.

2. In a barrel-washing machine provided with friction-rollers to rotate the barrel, the combination, with a suitable bed, of a vertical stanchion at each end of the bed, formed with two posts at the sides of an intermediate space B boxes I, formed in such stanchions and having recesses for roller-shaft bearings, bearings fitted within the same and secured removably therein, and adjusting-blocks for holding the bearings in either end of such recesses, as and for the purpose set forth.

3. In a barrel-washing machine provided with friction-rollers to rotate the barrel, the combination, with a suitable bed, of a vertical stanchion at each end of the bed, formed with two posts B at the sides of an intermediate space B boxes I, formed in such stanchions and having recesses open at their outer sides, bearings fitted to the recesses for parallel roller-shafts, caps I, provided with tongues i, projecting within the said recesses, and pins inserted through the sides of the box and through such tongues, as and for the purpose set forth.

In testimony whereof we have hereunto set our hands in the presence of two subscribing witnesses.
